Antioxidant and toxicological activities of Pyrossia lanceolata (L.) Farw. extracts

Background: Pyrrosia lanceolata (L.) farw. is one of the Polypodiaceae species that commonly used as a traditional medicinal plant. Objective: The purpose this study was to determine antioxidant and toxic levels in extracts species. Method: aerial portion specie extracted with methanol, followed by liquid-liquid extraction n-hexane, dichloromethane, ethyl acetate. DPPH radicals brine shrimp lethality test, , were assess its activity toxicity. Result: n-hexane extract exhibited no IC50 values exceeding 500 μg/mL, whereas acetate high level an value 12.08±0.27 μg/mL. Moreover, when tested against Artemia salina leach, toxicological greater than 1000 Conclusion: These findings lay groundwork for further investigation into process isolating evaluating biological secondary metabolites discovered extract.
